Through Hole Resistors (THRs) have been used in many types of applications for decades due to their reliable performance, low cost, and minimal footprint. The MBB02070C8254FC100, in particular, is a high power metal film THR with a maximum power rating of 1W. It is designed for military and aerospace applications where reliability and performance are essential. In this article, we\'ll explore the application fields and working principle of the MBB02070C8254FC100.

Application Fields

The MBB02070C8254FC100 THR is primarily used in military and aerospace applications that require a high power THR with reliable performance. Its low parasitic inductance makes it suitable for automotive, broadcast, and telecommunications applications. This THR has also been incorporated into many AC-DC and DC-DC power converters to help provide efficient power conversion and regulation.

The MBB02070C8254FC100 THR can also be used in low noise audio amplifier circuits to provide stable operation and low thermal noise. This THR is also well suited for RF circuits, providing excellent shielding and attenuation.

Working Principle

The MBB02070C8254FC100 THR is a high power metal film resistor with a thick-film substrate. The thick-film substrate provides superior environmental and temperature stability, as well as an overall lower temperature coefficient of resistance. The resistor is made up of an insulating substrate, a base metal layer, and a resistive film. The resistive film, which is typically manganese-nickel alloy, is deposited over the base metal, which is made up of either tungsten or titanium. This ensures a uniform and consistent resistance value.

The MBB02070C8254FC100 THR is a surface mounted device. This means it is soldered directly to an appropriate circuit board without the need to drill a hole through the board. This eliminates the need for specialized tools or additional manufacturing steps, making the THR easier to install. The THR is then connected to an appropriate power source, which is typically a DC voltage.

When the DC voltage is applied to the THR, the resistive film heats up and the resistance of the THR increases, which causes the voltage to drop. This is known as the load regulation effect of the THR. This helps to regulate the current flowing through the circuit, preventing overloading and protecting the circuit components from damage.

The MBB02070C8254FC100 THR is a durable and reliable THR that is used in a variety of applications. With its low parasitic inductance, temperature stability, and long reliability, it is an ideal THR for military and aerospace applications. It is also well suited for low noise audio amplifier circuits, as well as automotive, broadcast, and telecommunications applications.
